Thread: Samsung unified Driver fails

  1. #1

    Thumbs down Samsung unified Driver fails

    Installation of Samsung unified Driver fails in SUSE 11.0


    I istalled the Unified Driver for the Laser Multifunction SCX-4200 by means of the istaller program supplied with it. in my two computers, 32 and 64 bit

    The printer works fine, but the scanner is not detected.
    Following the terminal output


    linux-e1wc:/home/jcaser # sane-find-scanner

    # sane-find-scanner will now attempt to detect your scanner. If the
    # result is different from what you expected, first make sure your
    # scanner is powered up and properly connected to your computer.

    # No SCSI scanners found. If you expected something different, make sure that
    # you have loaded a kernel SCSI driver for your SCSI adapter.

    found USB scanner (vendor=0x04e8 [Samsung], product=0x341b [SCX-4200 Series]) at libusb:005:004
    # Your USB scanner was (probably) detected. It may or may not be supportedby
    # SANE. Try scanimage -L and read the backend's manpage.

    # Not checking for parallel port scanners.

    # Most Scanners connected to the parallel port or other proprietary ports
    # can't be detected by this program.

    linux-e1wc:/home/jcaser # scanimage -L

    No scanners were identified. If you were expecting something different,
    check that the scanner is plugged in, turned on and detected by the
    sane-find-scanner tool (if appropriate). Please read the documentation
    which came with this software (README, FAQ, manpages).

    Has anyone a suggestion?

    You may have to mount usbf: issue as root:

    'mount -t usbfs /proc/bus/usb usbfs` (or none)

    Works perfectly for my SCX-4200 on 32-bit 11.0, no idea if it will work
    on 64-bit, too.
    For some funny reason automounting in fstab with an entry
    usbfs /proc/bus/usb usbfs defaults,auto
    0 0
    does _not_ automount at boot (anybody any idea why this does not work
    ??), but followed by a (root) 'mount usbfs' both printer and scanner
    work fine.
    Cheers NB

    I have a Samsung ml-2510 and just use yast to install the drivers instead of the unified drivers on the cd. You could try it for yours

    Geoff, as far as I know there is no YAST supplied driver for the SCX-4200 MFP (in particular for the scanner part), so you can't but use the proprietary Samsung driver which does indeed work fine if you mount usbfs explicitly as described in a previous post.
    Cheers nb

    Danke Nikolaus
    Could you please elaborate the command a little more?
    I have introduced
    mount -t usbfs /proc/bus/usb usbfs
    but is munts nothing, since the computer says the mountigs point usbf does not exist.
    I would be very grateful if you coul give me a detailled explanation
    By the way I have tried to extract the dirver via CUPS from the delivered Samsumg package.This is possible for the printer, but not for the Sane program (or at least I was unable to find aut how it is done)
    Danke nochmals. Die Sau mssen wir schlachten

    Oh yes, the system is right (,of course ;-)),I typed the command in incorrect order, it should read:
    'mount -t usbfs usbfs /proc/bus/usb'
    Sorry for this error: since I have put the line I mentioned before into /etc/fstab I currently just use 'mount usbfs' so I didn't realize that I erroneously interchanged up 'device' and 'mountpoint'.
    In Deutsch:
    Das System hat - natürlich - recht, das command muss richtig lauten:
    'mount -t usbfs usbfs /proc/bus/usb'
    Da ich seit längerem eine etc/fstab Zeile wie oben erwähnt habe, brauche ich jetzt nur 'mount usbfs' zusagen, daher der 'Dreher' in meinem ersten posting.
    Ich hoffe jetzt klappt'S, viel Erfolg!

    Unhappy Re: Samsung unified Driver fails

    Thanks
    Now I can mount "mount -t usbfs usbfs /proc/bus/usb" without problems and the system says "ok".I have reinstalled the Samsung driver and now recognizes the SCX-4200 printer directly, without the detour over the YAST installer and the CUPS package, so it is an improvement.
    However,it does not recognize the scanner
    An inquire with Scanimage gives the following answer
    scanimage -L
    *** glibc detected *** scanimage: double free or corruption (!prev): 0x080556b8
    which is also some improvement over the last run without "mount -t usbfs usbfs /proc/bus/usb"

    Could you be so kind as to ive me a detailled secuency how to proceed?.

    Ich blicke jetz etwas mehr durch, danke.Dennoch mache ich wohl etwas falsch.Ich wre fr weitere Hilfe dankbar. Ich hoffe Ich falle nicht so auf dem Wecker.
    Danke

    Now I have tested "mount -t usbfs usbfs /proc/bus/usb" in the 64 bit computer and it works perfectly.50% of the problem is solved
    Thanks again.
    The devil knos why it does not work in the 32 bit computer
    Any Ideas?

    Good to hear things are improving (at least on your 64b machine). As to the persisting problem on your 32b system I unfortunately don't have any really new idea but can only recommend std procedures:
    1) Deinstall Samsung driver
    2) Make sure cups and sane are correctly installed at a reasonably current level (hopefully 32b system is pretty current, too)
    3) 'mount -t usbfs ...'
    4) Reinstall Samsung's (latest) driver ('20070720152943906 ....')

    Works perfect for my SCX-4200 on a couple of 32b systems (opensuse 10.2, 10.3, 11.0, Ubuntu 7.10, 8.04) both on old (2001/2) and new (2007) PC-HW.
    Good luck!
